"Those not able to work were marched to the farmhouses. These were a good kilometer from the side track. There they were made to undress. At first they had to undress in the open, where we had erected walls made of straw and branches of trees that kept them from onlookers. After a while we built barracks. We had big signs, all of which read 'To Disinfection' or 'Baths.' That was in order to give the people the impression that they would merely receive a bath or be disinfected, in order not to have any technical difficulty in the extermination processes."

“When in the summer of 1941 he gave me the order to prepare installations at Auschwitz where mass exterminations could take place, and personally to carry out these exterminations, I did not have the slightest idea of their scale or consequences. It was certainly an extraordinary and monstrous order. Nevertheless the reasons behind the extermination programme seemed to me right. I did not reflect on it at the time: I had been given an order, and I had to carry it out. Whether this mass extermination of the Jews was necessary or not was something on which I could not allow myself to form an opinion, for I lacked the necessary breadth of view.”

“We cut the hair from women after they had been exterminated in the gas chambers. The hair was then sent to factories, when it was woven into special fittings for gaskets.”

“They developed out of the situation. The courts brought in a lot of people who had to be shot. I always objected to having to use the same men for firing squadrons over and over again. During that period one day my camp leader, Karl Fritzsch, came to me and asked me whether I could try to execute people with Zyklon B gas. Until that time, Zyklon B was used only to disinfect barracks which were full of insects, fleas, et cetera. I tried it out on some people sentenced to death in the cell prison and that is how it developed. I didn't want any more shootings, so we used gas chambers instead.”

“He struck me as a normal person that's the horrible thing about it. If he had been a monster you know if he'd gone in there like "I did.. I killed all these people. It was my war duty." But he just acted like an unimportant individual. He just answered the questions. Without emotion. Without emotion. Not in the slightest apologetic. Though I think there was a sense of pride. A sense of pride.”

“Burning 2000 people took about 24 hours in the five stoves. Usually we could manage to cremate only about 1700 to 1800. We were thus always behind in our cremating because as you can see it was much easier to exterminate by gas than to cremate, which took so much more time and labor.”

“This mass extermination, with all its attendant circumstances, did not, as I know, fail to affect those who took part in it. With very few exceptions, nearly all those detailed to do this monstrous "work," and who, like myself, have given sufficient thought to the matter, have been deeply marked by these events. Many of the men involved approached me as I went my rounds through the extermination buildings, and poured out their anxieties and impressions to me, in the hope that I could allay them. Again and again during these confidential conversations I was asked; is it necessary that we do this? Is it necessary that hundreds of thousands of women and children be destroyed? And I, who in my innermost being had on countless occasions asked myself exactly this question, could only fob them off and attempt to console them by repeating that it was done on Hitler's order. I had to tell them that this extermination of Jews had to be, so that Germany and our posterity might be freed for ever from their relentless adversaries. There was no doubt in the mind of any of us that Hitler's order had to be obeyed regardless, and that it was the duty of the SS to carry it out. Nevertheless we were all tormented by secret doubts.”
